From d9b9fc6b5b56633edd136536aea68a03fa33bd0f Mon Sep 17 00:00:00 2001 From: Paul Eggert Date: Wed, 17 Sep 2003 22:35:01 +0000 Subject: [PATCH] (gl_USE_SYSTEM_EXTENSIONS): Call AC_BEFORE first, to avoid spurious warnings like "AC_RUN_IFELSE was called before gl_USE_SYSTEM_EXTENSIONS" from autoreconf. Add copyright notice. Put AC_GNU_SOURCE before AC_AIX (to indicate relative importance :-). --- m4/extensions.m4 | 18 +++++++++++++++--- 1 file changed, 15 insertions(+), 3 deletions(-) diff --git a/m4/extensions.m4 b/m4/extensions.m4 index 95a54a6f10..58bc0beb6d 100644 --- a/m4/extensions.m4 +++ b/m4/extensions.m4 @@ -1,17 +1,29 @@ +# Enable extensions on systems that normally disable them. + +# Copyright (C) 2003 Free Software Foundation, Inc. + +# This file is free software, distributed under the terms of the GNU +# General Public License.
